Data on moisture sources, winter condensation potential, C02 levels, levels of biological contamination and blood lymphocytes from fifty nine houses subjected to detailed testing and inspection in a previous phase of the Wallaceburg study were subject to more detailed statistical evaluation to determine the relationships between moisture sources, fungal growth and objective measures of health.
Three different examples illustrate the possibilities offered by the use of tracer gas methods for detailed airborne moisture transport studies in building. The first one concerns an individual dwelling with severe condensation problems, the second one gives an example of statistical data collection of humidity related parameters in 18 apartments and the last one focuses on the evaluation of the amount of water evaporating from the building materials of a recently built low energy dwelling and on the energy consumption required for drying the construction.
